Olga rubbed her temple with her index finger a couple of times. “I understand. I’ll try to get her address without mentioning your name. I’ll think of a good way. Can you tell me her name?”

Tsukuru wrote down Kuro’s name in her memo pad.

“What’s the name of the town your high school was in?”

“Nagoya,” Tsukuru told her.

Olga took his cell phone again and dialed the number given on the answering machine. The phone rang a few times, and then someone answered. Olga spoke to the person in Finnish, using a friendly tone. She explained something, the other person asked her a question, and again she gave a concise explanation. She said the name Eri several times. After a few rounds of this, the other person seemed convinced. Olga picked up her ballpoint pen and noted something down. She politely thanked the person and hung up.

“It worked,” she said.

“I’m glad.”

“Their last name is Haatainen. The husband’s first name is Edvard. He’s spending the summer at their lakeside cottage outside a town called Hämeenlinna, northwest of Helsinki. Eri and the children are with him, of course.”

“How did you find that out without mentioning my name?”

Olga smiled impishly. “I told a tiny lie. I pretended to be a FedEx delivery person. I said I had a package addressed to Eri from Nagoya, Japan, and asked him where I should forward it. Her husband answered the phone and didn’t hesitate to give me the forwarding address. Here it is.”

She passed him a sheet from her memo pad. She stood up, went over to the concierge desk, and got a simple map of southern Finland. She spread the map open and marked the location of Hämeenlinna.

“Here’s where Hämeenlinna is. I’ll look up the address of their summer cottage on Google. The office is closed now, so I’ll print it out tomorrow and give it to you then.”

“How long would it take to get there?”

“Well, it’s about 100 kilometers, so from here by car you should allow about an hour and a half. The highway runs straight there. There are trains, too, but then you’d still need a car to get to their house.”

“I’ll rent a car.”

“In Hämeenlinna there’s a lovely castle by the lakeside, and the house where Sibelius was born. But I imagine you have more important matters. Tomorrow why don’t you come by the office whenever’s convenient for you? We open at nine. There’s a car rental place nearby, and I’ll take care of renting a car for you.”

“You’ve been a big help,” Tsukuru said, thanking her.

“A good friend of Sara’s is a friend of mine,” Olga said, and winked. “I hope you can meet Eri. And that she’ll be surprised.”

“I hope so. That’s really why I came here.”
